Need your help for ID...

I get some Caranx sexfasciatus, and... found one pcs of below in the same bag...
Can somebody told me the species name?

I think it's a cool fish with a very big mouth, however, I think it should be a marine fish.
It still alive in freshwater around 10days, however, never saw it eat anything...

They look like they're from Carangidae, but it's kinda hard to tell. What size are they?
